Unnecessary messages come in plenty on a daily basis and often they can be very annoying if you are in the middle of something, especially if the person doesn't stop at one message. While WhatsApp already has a block option, the Meta-owned messaging application is now reportedly working on a new 'Block' shortcut feature that will provide users a block shortcut right within the notifications. 

The platform is planning to introduce this new block shortcut within notifications but not always -- the block shortcut will be visible only when users receive a message from unknown and untrusted contacts, reports WABetaInfo.

This limitation is needed as users might tap on the block action by accident when replying to notifications to their trusted contacts.
